ALBERT J. SApYEBS, OF CHICAGO, ILLINOIS, ASSIGNOR TO LINK-BELT COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

Lomme Boom.

Application led Hatch 12, 1923. Serial No. 624,337.

To all whom it my coatcem:

Be it known that I, ALBERT J. Sams, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Loading Booms, of which the following is a specification.

M invention relates to a loading boom for oading coal or other similarly divided substances upon cars, and has articular relation to a boom adapted to deliver such materials to a train consistin partly of open to ped cars and partly o box cars. Anot e" object is to provide a loading boom adapted to receive material at a point to one side of the track along which the cars pass and at a level lower than the tops of the cars. Another object is to provide a boom adapted to minimize the breakage of the coal at the point where the coal is delivered to the boom and at the point where the coal is delivered from the boom to the car. Other objects will appear from time t`o time in the course of the specification and claims.

I illustrate my invention more or less diagrammatically in the accompanying drawin whereinigure 1 is a side elevation with parts in section.

Fi ure 2 is a plan view.

Lie parts are illustrated by like symbols throughout the specification and drawings.

A, A are the frame members of any suitable ti ple or supporting structure, the details oi) which form no part of the present invention. A1 is the delivery end of any suitable shaking chute or screen down which asses the material to be delivered, herein illustrated as a relatively broad screen.

B is a horizontally supported loading boom section which is pivoted as at B1 in the yoke B2 which in turn is swiveled or pivoted u on the vertical element Bs and is su porte upon the block B* which is provi ed with any suitable bearing surface or member B.

The outer end of the boom section may be supported by any means adaptedto maintain the boom in horizontal position, While permitting free rotation about its vertical pivot. I illustrate, however, the arcuate track C overlying the boom and supported, for example, at one end upon the horizontal frame member C1 and at the other upon the transversal framemember C2 supported in turn upon the upright members C at both sides o the track. Adapted to travel along the arcuate track C is a trolley member C*s which is provided with a depending flange C*s and upwardl projecting arms C", terminating in rollers C8 which engage the lower flange of the track C. C9 is a supporting frame secured adjacent the outer end of the boom section B and connected to the trolley element, for example, by the rods C1". Any suitable means may be rovided for moving the trolley element a on the track or for otherwise rotating the om section B about its vertical pivot.

However, I illustrate herein a cable H running about sheaves or pulleys H1 and secured at each end to the trolley member C5. Any suitable means may be used to drive one of the pulleys H1, which may be associated with a drive pulley H3 about which passes the belt H to any suitable power source.

lrVhile I have illustrated an over-lying track, it is obvious that the boom might be supported by an arcuate track lying at the same level as the track u on which the railroad cars run, the boom eing supported b any suitable relatively rigid support which is shaped to permit the outer end of the boom to swing out over the car as illustrated in Figure 1.

D is an outer or terminal boom section pivoted to the section B as at D1. I rovide any suitable tackle whereby the inc ination of the section D in relation to the section B may be controlled at will. The up er end of said tackle mi ht be adapted to r1 e along the arcuate trac in unison with the movement of the boom B, but I have illustrated a separate transverse track D5 along which travels a trolley element D which is connected by any suitable tackle D1 with the yoke D pivoted to the outer end of said section D.

E is any suitable mot'ive means mounted upon the boom and adapted to drive, through the gears E, E1, E2, the conveyor sprocket E3 to ro el the endless conveyor E which exten s t ereabout and thence to the end of the boom section D where it passes about the terminal sprocket E1. Any suitable supporting means may be rovided for the conveyor, the details of which form no art of the present invention.

, F are the railroad tracks along which the cars to be loaded pass and F1 is a diagrammatically illustrated open topped car. K is any suitable picking table mounted upon or along the ma n boom section B.

It will be realized that while I have illustrated a working device, many chan es mi ht be made in the size, shape, num er an disposition of parts Without departing from the spirit of my invention.

The use and operation of my invention are as follows:

It is frequently necessary to coal a mixed train of open and closed` cars. The direct loading boom normally used for coaling open cars is in many instances not suited for coaling the closed car. If the loading boom is mounted above and in line with the track, it will conveniently drop coal into the top of an open car, but it is not conveniently located for deliverin coal into the side door of a closed car. n some cases, moreover, the

oint of delivery of the coal to the boom is ower than the necessary point of clearance for a closed car. I have provided a loading boom which will fill open and closed oars with equal facility and which is adapted to receive coal from a point lower than the top of a closed car.

Preferabl I employ a boom provided with an endless elt or conveyor which receives coal at one end of the boom and conveys it along the boom, regardless of the angle at which the boom is positioned and deposits it in the opposite end of the boom.

In order to minimize breakage at the point where the coal is delivered to the boom, I provide a boom consisting of two sections, the inner or primary section being pivoted on a vertical axis adjacent the end of the coal delivery screen or chute, but so mounted at its outer end as to be held continuously in a horizontal plane. Thus even where a broad screen is used, its delivery oint can be placed so close to the top o the loading boom that there is relatively no breakage. Where an inclined boom is used, or a boom rotatable about a horizontal axis, there would be interference between the boom and the screen or chute. Furthermore, while the coal at the side of the screen nearest the pivot of the chute might drop without breakage, the inclination of the boom would produce a larger and often damaging drop at the opposite edge of the screen.

The horizontal boom section is mounted at a height suilicient to clear the top of au open coal car and is pivoted on a vertical axis at its end adjacent the coal screen. I have illustrated an over-lying track supporting the outer end of the horizontal section, but it obviously might be supported by a track upon the ground level, the essential point being that means are provided for supporting the boom in a horizontal plane and for swinging it out over the top of an open coal car, the boom being verticall pivoted at a point to one side of the trac along which the coal cars are conveyed.

To enable the coal to be delivered without breakage to the interior of the coal car, I provide a boom with an end section pivoted orizontally to the horizontal section and rovided with an over-lying track and hoisting means for raising and lowering it. Thus the boom can deliver coal without breakage to cars of varying floor levels.

In coaling a mixed train, when an open topped car has been coaled and is followed by a closed car, the end section is raised to clear the top of the car and the whole boom is swung to one side of the track in osition parallel with the train. The close car is then spotted with its door way adjacent the end of the boom. Coal is then conveyed along the boom and deposited in any suitable chute whereby it is delivered to the interior of the closed car, and thereby distributed in final position,either by manual labor or by any suitable coaling machine, the details of which form no part of the present invention. The position of the boom and of the supplementary coaling means are shown in dotted lines in Figures 1 and 2.

I provide a picking table mounted along a horizontal boom section, and if desired, the coal may be picked by workmen standing upon it as it passes along the boom.

I claim:
